Prefabricated tunnel track unit, prefabricated tunnel track and deformation maintenance method of prefabricated tunnel track
The invention discloses a prefabricated tunnel track unit, a prefabricated tunnel track and a deformation maintenance method of the prefabricated tunnel track, and relates to the field of railway tracks. The prefabricated tunnel track unit comprises at least two blocking tables, a prefabricated long sleeper, a prefabricated track plate, a cast-in-place layer arranged between the prefabricated track plate and an inverted arch of a tunnel, and an elastic vibration reduction layer. The at least two blocking tables are arranged at intervals and form a limiting space used for limiting the prefabricated track plate. A rail bearing table is arranged on the upper surface of the prefabricated long sleeper, and fasteners are arranged on the surface of the rail bearing table. The prefabricated trackplate comprises two track plate units and a connecting piece, the two track plate units are arranged at an interval and form a mounting groove for accommodating the prefabricated long sleeper, the connecting piece is arranged in the gap between the two track plate units and connects the two track plate units, each track plate unit is provided with a first notch matched with the corresponding blocking table, and the gap between the prefabricated long sleeper and the mounting groove is filled with the elastic vibration reduction layer. The prefabricated tunnel track unit has good vibration reduction and noise reduction functions and deformation adjustment capacity, the construction difficulty can be reduced, and the construction efficiency is high.
一种装配式隧道轨道单元、装配式隧道轨道及其变形维修方法，涉及铁路轨道领域。装配式隧道轨道单元包括至少两个挡台、预制长枕、预制轨道板、设置于预制轨道板与隧道的仰拱之间的现浇层及弹性减振层。至少两个挡台间隔设置并形成用于限定预制轨道板的限位空间。预制长枕的上表面设有承轨台，承轨台的表面设有扣件。预制轨道板包括两个轨道板单元和连接件，两个轨道板单元间隙布置并形成容纳预制长枕的安装槽，连接件设置于两个轨道板单元的间隙处并连接两个轨道板单元，每个轨道板单元设有与挡台配合的第一缺口，弹性减振层填充于预制长枕与安装槽的缝隙中，其具有良好的减振降噪功能、变形调整能力，能够降低施工难度且施工效率高。
